ARMORMAX® can withstand repeated thermal cycling, mechanical impact and abrasion due to its high reinforcing needle content.

The metal fibers are pre-blended and uniformly distributed in the refractory matrix.


  • High fracture toughness when thermally cycled
  • Low abrasion loss
  • High mechanical impact resistance
  • Well suited for applications up to 1200°C (2200°F) continuous exposure
  • Characterized for low water requirements (ranging from 4.5% to 6.5% by weight)
  • All versions are low-cement castables
  • Excellent flowability for high wire-containing refractory ceramic castables
